本文应用经颅多普勒(TCD)、脑干听觉诱发电位(BAEP)对59例中老年发作性眩晕患者进行了对照研究。结果表明:慢性脑供血不足患者之眩晕多属前庭周围性,其病变血管广泛,主要累及基底动脉、椎动脉及大脑中动脉;而基底动脉系短暂缺血发作患者之眩晕属前庭中枢性,其病变仅限于基底动脉和椎动脉,但后者椎动脉缺血程度重于前者。
In this paper, 59 cases of middle-aged and elderly patients with onset of vertigo were studied by transcranial Doppler (TCD) and brainstem auditory evoked potentials (BAEP). The results showed that: Vertigo in patients with chronic cerebral insufficiency mostly belong to the vestibular circumferences, the extensive vascular lesions, mainly involving the basilar artery, vertebral artery and middle cerebral artery; while patients with basilar artery transient ischemic attack is vestibular center, its Lesions were limited to the basilar artery and vertebral artery, but the latter was more severe than the former vertebral artery ischemia.
